By default, the India team that played the first ODI would be the most inexperienced India team ever.

But i am inclined to believe that leaving those initial stats asides, this India team (that played ODI 3 of current India-SL series) is the youngest (in terms of age) and most inexperienced (in terms of collective number of ODIs played) ever.

Team to play the ODI 1 looked like the youngest in terms of age and then one to play ODI 3 looks to be the most inexperienced in terms of collective number of ODIs played and average no of ODIs per player.

In fact, i think (i didn't bother the cricinfo) that this team maybe more inexperienced than the current BD team.

In any case, this India team hasn't done worse than their experienced and elite-laden team of the past as yet though it looks terminally short of talents unlike their predecessors.
